What is immune complex mediated glomerulonephritis?

Immune-complex-mediated membranoproliferative glomerulonephritis (MPGN) is a new concept that refers to MPGN with immunoglobulin and C3 deposition in the kidney based on immunofluorescence examination. It is associated with pathological autoantibodies production.

What causes immune mediated glomerulonephritis?

Glomerulonephritis occurs when immune complexes (mixtures of antibodies and antigens) are filtered out of the bloodstream and become trapped within the glomeruli. When these compounds are trapped, the body responds by activating its immune defenses, resulting in further damage to the glomeruli.

How immune complexes cause glomerular injury?

Immune complexes can damage glomerular structures by attracting circulating inflammatory cells or activating resident glomerular cells to release vasoactive substances, cytokines, and activators of coagulation.

What causes immune complex deposition?

Immune complex deposition is a prominent feature of several autoimmune diseases, including rheumatoid arthritis, scleroderma and Sjögren’s syndrome. An inability to degrade immune complexes in the lysosome and subsequent accumulation on the surface of immune cells has been associated with systemic lupus erythematosus.

What are the symptoms of glomerulonephritis?

Early signs and symptoms of the chronic form may include: Blood or protein in the urine (hematuria, proteinuria) High blood pressure. Swelling of your ankles or face (edema)…Symptoms of kidney failure include:

  • Lack of appetite.
  • Nausea and vomiting.
  • Tiredness.
  • Difficulty sleeping.
  • Dry and itchy skin.
  • Nighttime muscle cramps.

Is glomerulonephritis immune-mediated?

Glomerulonephritis is a renal disease in which immune-mediated glomerular damage is the initiating factor. The hallmark of glomerulonephritis is increased permeability of the glomerular barrier.

What do immune complexes consist of?

Introduction: Immune complexes are macromolecules consisting of immunoglobulins (antibodies) bound to different antigens [1].

What is an example of an immune complex mediated disease?

These diseases include rheumatoid arthritis, where an inflammatory response is induced by antibody–antigen complexes in the synovial fluid; types of glomerulonephritis, due to complex trapping within the glomerulus, or retention of antibody-antigen in the glomerulus; extrinsic allergic alveolitis, as in “farmer’s lung” …
